1 D-Bus 1.5.6 (UNRELEASED)
4 Potentially incompatible (Bustle and similar debugging tools will need
5 changes to work as intended):
7 • Do not allow match rules to "eavesdrop" (receive messages intended for a
8 different recipient) by mistake: eavesdroppers must now opt-in to this
9 behaviour by putting "eavesdrop='true'" in the match rule, which will
10 not have any practical effect on buses where eavesdropping is not allowed
11 (fd.o #37890, Cosimo Alfarano)
15 • Use DBUS_ERROR_OBJECT_PATH_IN_USE if dbus_connection_try_register_object_path
16 or dbus_connection_try_register_fallback fails, not ...ADDRESS_IN_USE,
17 and simplify object-path registration (fd.o #38874, Jiří Klimeš)
19 • Consistently use atomic operations on the refcounts of DBusPendingCall,
20 DBusServer, DBusMessageFilter and DBusObjectTree, as was done for
21 DBusConnection in 1.4.12, and make the use of atomic operations
22 more thorough for DBusConnection (fd.o #38005, Simon McVittie)
24 • Fix a file descriptor leak when connecting to a TCP socket (fd.o #37258,
27 • Make "make check" in a clean tree work, by not running tests until
28 test data has been set up (fd.o #34405, Simon McVittie)
30 • The dbus-daemon no longer busy-loops if it has a very large number of file
31 descriptors (fd.o #23194, Simon McVittie)
33 • Some cmake fixes (Ralf Habacker)
35 • Remove dead code, mainly from DBusString (fd.o #38570, Simon McVittie)
37 • Stop storing two extra byte order indicators in each D-Bus message
38 (fd.o #38287, Simon McVittie)
40 • Add an optional Stats interface which can be used to get statistics from
41 a running dbus-daemon if enabled at configure time with --enable-stats
42 (fd.o #34040, Simon McVittie)
44 • Documentation (fd.o #36156, Simon McVittie):
45 · let xsltproc be overridden as usual: ./configure XSLTPROC=myxsltproc
46 · install more documentation automatically, including man2html output
47 · put dbus.devhelp in the right place (it must go in ${htmldir})
49 • Unix-specific (fd.o #33465, Simon McVittie):
50 · opt-in to fd passing on Solaris
52 • Windows-specific (Ralf Habacker):
53 · fix use of a mutex for autolaunch server detection
54 · don't crash on malloc failure in _dbus_printf_string_upper_bound
56 D-Bus 1.5.4 (2011-06-10)
59 Security (local denial of service):
61 • Byte-swap foreign-endian messages correctly, preventing a long-standing
62 local DoS if foreign-endian messages are relayed through the dbus-daemon
63 (backporters: this is git commit c3223ba6c401ba81df1305851312a47c485e6cd7)
64 (CVE-2011-2200, fd.o #38120, Debian #629938; Simon McVittie)
68 • The constant to use for an infinite timeout now has a name,
69 DBUS_TIMEOUT_INFINITE. It is numerically equivalent to 0x7fffffff (INT32_MAX)
70 which can be used for source compatibility with older versions of libdbus.
72 • If GLib and DBus-GLib are already installed, more tests will be built,
73 providing better coverage. The new tests can also be installed via
74 ./configure --enable-installed-tests
75 for system integration testing, if required. (fd.o #34570, Simon McVittie)
79 • Consistently use atomic operations for the DBusConnection's refcount,
80 fixing potential threading problems (fd.o #38005, Simon McVittie)
82 • Don't use -Wl,--gc-sections by default: in practice the size decrease is
83 small (300KiB on x86-64) and it frequently doesn't work in unusual
84 toolchains. To optimize for minimum installed size, you should benchmark
85 various possibilities for CFLAGS and LDFLAGS, and set the best flags for
86 your particular toolchain at configure time. (fd.o #33466, Simon McVittie)
88 • Use #!/bin/sh for run-with-tmp-session-bus.sh, making it work on *BSD
89 (fd.o #35880, Timothy Redaelli)
91 • Use ln -fs to set up dbus for systemd, which should fix reinstallation
92 when not using a DESTDIR (fd.o #37870, Simon McVittie)
94 • Windows-specific changes:
95 · don't try to build dbus-daemon-launch-helper (fd.o #37838, Mark Brand)
97 D-Bus 1.5.2 (2011-06-01)
100 The "Boar Hunter" release.
102 Notes for distributors:
104 This version of D-Bus no longer uses -fPIE by default. Distributions wishing
105 to harden the dbus-daemon and dbus-launch-helper can re-enable this if their
106 toolchain supports it reliably, via something like:
108 ./configure CFLAGS=-fPIE LDFLAGS="-pie -Wl,-z,relro"
110 or by using distribution-specific wrappers such as Debian's hardening-wrapper.
114 • D-Bus Specification v0.17

116 (fd.o #34529, Simon McVittie)
117 · Define the ObjectManager interface (fd.o #34869, David Zeuthen)
118 • Don't force -fPIE: distributions and libtool know better than we do whether
119 it's desirable (fd.o #16621, fd.o #27215; Simon McVittie)
120 • Allow --disable-gc-sections, in case your toolchain offers the
121 -ffunction-sections, -fdata-sections and -Wl,--gc-sections options
122 but they're broken, as seen on Solaris (fd.o #33466, Simon McVittie)
123 • Install dbus-daemon and dbus-daemon-launch-helper in a more normal way
124 (fd.o #14512; Simon McVittie, loosely based on a patch from Luca Barbato)
125 • Ensure that maintainers upload documentation with the right permissions
126 (fd.o #36130, Simon McVittie)

133 • Make the nonce-tcp transport work on Unix (fd.o #34569, Simon McVittie)
134 • On Unix, if /var/lib/dbus/machine-id cannot be read, try /etc/machine-id
135 (fd.o #35228, Lennart Poettering)
136 • In the regression tests, don't report fds as "leaked" if they were open
137 on startup (fd.o #35173, Simon McVittie)
138 • Make dbus-monitor bail out if asked to monitor more than one bus,
139 rather than silently using the last one (fd.o #26548, Will Thompson)
140 • Clarify documentation (fd.o #35182, Simon McVittie)
141 • Clean up minor dead code and some incorrect error handling

156 (fd.o #24317, #34870; Will Thompson, David Zeuthen, Simon McVittie)
157 · Make argNpath support object paths, not just object-path-like strings,
158 and document it better (fd.o #31818, Will Thompson)
159 • Let the bus daemon implement more than one interface (fd.o #33757,
161 • Optimize _dbus_string_replace_len to reduce waste (fd.o #21261,
163 • Require user intervention to compile with missing 64-bit support
164 (fd.o #35114, Simon McVittie)
165 • Add dbus_type_is_valid as public API (fd.o #20496, Simon McVittie)
166 • Raise UnknownObject instead of UnknownMethod for calls to methods on
167 paths that are not part of the object tree, and UnknownInterface for calls
168 to unknown interfaces in the bus daemon (fd.o #34527, Lennart Poettering)

173 The "It's like the beginning of a lobster" release.

177 • Correctly give XDG_DATA_HOME priority over XDG_DATA_DIRS (fd.o #34496,
179 • Prevent X11 autolaunching if $DISPLAY is unset or empty, and add
180 --disable-x11-autolaunch configure option to prevent it altogether
181 in embedded environments (fd.o #19997, NB#219964; Simon McVittie)
182 • Install the documentation, and an index for Devhelp (fd.o #13495,
183 Debian #454142; Simon McVittie, Matthias Clasen)
184 • If checks are not disabled, check validity of string-like types and
185 booleans when sending them (fd.o #16338, NB#223152; Simon McVittie)
186 • Add UnknownObject, UnknownInterface, UnknownProperty and PropertyReadOnly
187 errors to dbus-shared.h (fd.o #34527, Lennart Poettering)
188 • Break up a huge conditional in config-parser so gcov can produce coverage
189 data (fd.o #10887, Simon McVittie)
190 • List which parts of the Desktop Entry specification are applicable to
191 .service files (fd.o #19159, Sven Herzberg)
192 • Don't suppress service activation if two services have the same Exec=
193 (fd.o #35750, Colin Walters)
195 · Avoid the name ELEMENT_TYPE due to namespace-pollution from winioctl.h
197 · Include _dbus_path_is_absolute in libdbus on Windows, fixing compilation
198 (fd.o #32805, Mark Brand)

206 which were mistakenly included in 1.4.4
208 D-Bus 1.4.4 (2010-02-17)
211 • Switch back to using even micro versions for stable releases; 1.4.1
212 should have been called 1.4.2, so skip that version number
213 • Don't leave bad file descriptors being watched when spawning processes,
214 which could result in a busy-loop (fd.o #32992, NB#200248; possibly
215 also LP#656134, LP#680444, LP#713157)
216 • Check for MSG_NOSIGNAL correctly

221 fd.o #33128, fd.o #33277, fd.o #33126, NB#180486)

246 D-Bus 1.4.1 (20 December 2010)
249 • Fix for CVE-2010-4352: sending messages with excessively-nested variants can
250 crash the bus. The existing restriction to 64-levels of nesting previously
251 only applied to the static type signature; now it also applies to dynamic
252 nesting using variants. Thanks to Rémi Denis-Courmont for discoving this
254 • OS X portability fixes, including launchd support.
255 • Windows autolaunch improvements.
